1.Poor communications betweendisciplines and functions

2.Concurrent engineering

3.Fast-track projects

4.Limited resources

5.Ageing skilled workforce

6.Schedule / install by area –test and turnover by systems

7.Short time betweenAFC/IFC and construction

8.Many revisions

9.Operate in “scramble” mode and work with whatever is available

a) Engineering deliverables

b) Materials availability

c) Allocation of materials

d) Fabrication deliverables

Common Questions

What is the exact progress to date?

Is the planned schedule

achievable?

What effort is needed to complete?

How will theschedule be kept

given the changing circumstances?

How will engineering changes affect work

content, cost and schedule?

What will bethe project impact be if materials are delayed?

ConstructSim Approach

• Drive priorities based on “ideal” construction sequence basedon turnover systems

• Expedite both engineering and fabrication to deliver against ideal plan

• Allocate materials based on priorities

• Accurately track effort for completion

• Manage work-fronts effectively as constraints change on site

Diesel Refinery: $2M Savings in Mechanical Sub Change Orders

– New Refinery Unit - TIC $320M

– Lump Sum Contract with Mechanical Sub

– ConstructSim Pipe purchased by Owner and

utilized by Construction Management firm

– Excessive change order submitted by

Mechanical Sub

– Actual progress not in alignment with

progress reported

– ConstructSim used to analyze change order

and update progress reporting system

“ ConstructSim enabled

us to recover project

schedule losses, and

complete on time -

without paying for

unwarranted change

orders.”

Claim: $2.5M

Settled: $0.5M

– Deepwater Offshore Platform - $150M

– Time and materials contract with Fab Yard

– ConstructSim Pipe purchased by Owner and

utilized by module Fab Yard contractor

– ConstructSim used to re-baseline

project schedule

– Development of crew-level work face

plans with ConstructSim

– Project completes on time, under budget,

and sails away with only 7 punch list items

(compared to 1000’s for other projects)

Background

ConstructSim Use Case

Offshore Platform: Saved $17M, Reduced Schedule 3 Mon ths

“ The labour efficiency

we obtained using

ConstructSim enabled

us to save 3 months

and U.S.$17M, as well

as reduce the punch list

items by over 99%.”
